SPECIFICATION formingpart of Letters Patent N0, 258,013, dated May 16,1882,

Application tiled March 11, 1882.

- and exact description of theinvention, which will enable othersskilled in the art to which it appertains to make and use the same,refer ence being had to the accompanying drawings, which form apart ofthis specification.

Figure 1 is a perspective view of my improved machine for cutting straw,tobacco, &c. Fig. 2 is a vertical sectional view taken longitudinallythrough the main shaft. Fig. 3 is a longitudinal sectional view of themachine; and Fig. 4 is a' section on the line a; .90, Fig. 3.Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to machines for cutting straw, tobacco, 850.; andit consists in certain improvements in the construction of the samewhichwill be hereinafter fully described, and particularly pointed out in theclaim.

In the drawings hereto annexed, A represents a suitably-constructedframe, the sides of which are provided with boxes. or bearings for themain shaft B. Mounted securely upon the main shaft is a disk orhub,O,having arms D D, which project in opposite directions. The arms Dare provided at their ends with boxes E, in which the short transverseshafts F are journaled, the bearings for said shafts being formed byblocks Gr, adjustable in the boxes E by set-screws H. The shafts F carryat their front ends the circular knives or cutters I and at their rearends pulleys or bandwheels J, connected by bands or belts K K.

a with an a'nnularly-grooved disk, L, secured to the side of the frameA, as shown. By this arrangement, when the main shaft is revolved theshaftsF, carryingthe circular cutter,will be M, so that it may slidevertically.

(Model) Q is a cross-bar arranged under box M, and havingupward-projecting arms R, provided at their upper ends with hooks Shooking upon the shaft of the upper feed roll. Springs T, coiled uponthe arms It, are interposed between the cross-bar Q and the bottom ofbox M, (or under side of the frame A,-) thus forcing the said cross-barQ, arms It, and the upper feedroll in a downward direction.

' U is-a plate arranged in box M in rear of the feed-rolls, and havingarms or studs'V projecting into vertical slots W in the sides of saidbox, in which the said plate may thus slide.

vertically. The front side of plate U is beveled at X, so that thematerial to be cut will readily pass from between the feed-rollers undersaid plate, which, by suitablyarranged springs Y, is forced in adownward direction, so as to hold "the material securely while being cutby the rotary knives, which havebeen above described, and which ofcourse must be so adjusted as to sweep by the discharge end of the box.

Journaled in suitable hearings on the front side of frame A are a pairof short shafts,Z Z, having intermeshing pinions A. The shafts Z areconnected by universal couplingjoints B and rods 0 with the shafts ofthe feed-rolls, which are in this manner operated, the upper feed-roll,owing to the universal couplin g-joint, operating equally well at anyposition which it may happen to. occupy in relation to the lowerfeed-roll. Oneof the shafts Z has a bevel-gear, D, meshing with apinion, E, upon a short shaft, F, carrying at its'rear end africtionwheel, G. The latter is operated intermittingly by means ofcurved or concave shoes H, secured upon the arms D of the main shaft B,and having rubbcrcushions or blocks I, which, by coming in contact withthe friction-wheel G, turn itfor a distance regulated by the length ofsaid blocks, thus operating the feed mechanism. i

By regulating the size of the blocks 1 the length of the feed may ber,egulated,and it will be observed that owing to the constructiondescribed the material to be cut is only fed when .the knives or cuttersare at the greatest distance from the feed-box. At all other times it isstationary.

Having thus described my invention, I claim and desire to secure byLetters Patent "of the United States-- The combination ofthefeed-r01lers,thecoup- In testimony that I claim the foregoing as lings BO, the shafts Z, having intermeshing my own- I have hereto affixed mysignature in pinions A and bevel-gear D, the shaft F, havpresence of twowitnesses. ing pinion E and friction-wheel G, and the AUGUST BRANDT.
